Brand: Redcat Racing
SKU: RER07387

1/10 scale · buggy · RER07387

Redcat Racing's Blackout XBE is a four-wheel-drive 1/10 buggy, sold ready to run with a 550 brushed motor of 16 turns and a waterproof brushed speed control.

The 18T pinion drives a 55T spur, and the 109 mm tires sit on 12 mm hexes. The buggy measures 427 mm long on a 290 mm wheelbase. The speed control accepts up to a 3S pack, but a brushed motor on a bigger pack runs hotter, so check it by touch after the first few runs. If it is too hot to hold, a smaller pinion on the 3.2 mm motor shaft brings the temperature down.

Specifications

Last modified Oct 2, 2026

Spec	Value	Basis
Vehicle
Class The kind of vehicle the maker sells it as. It sets what the car is built to do and which cars it is fair to compare it with. Buggies are low, light off-road cars built for jumps and fast corners on dirt, clay or turf tracks. Drive All four wheels are driven. That gives more grip under power, especially on loose ground. The cost is more parts to maintain. Power A brushed motor carries current through carbon brushes that rub on the commutator. It is cheaper and smooth at low speed. The brushes wear and the motor loses power over time. Build Ready to run: built at the factory with the electronics installed. Some come without a battery or charger; the maker's box contents say which. Scale The maker's nominal size compared with a full-size vehicle. It works more as a class label than a measurement. A 1/10 monster truck is far bigger than a 1/10 touring car, so compare length and weight for real size. This one is 427 mm long. Part number The maker's product number for this exact version. A V2, a new color, or a kit instead of an RTR usually has a different number, and parts can differ between them. Check it against your box or receipt before ordering parts.

Drivetrain
Pinion The small gear on the motor shaft. Fewer teeth gear the car shorter: quicker acceleration, lower top speed and a cooler motor. More teeth do the opposite. On this car one tooth changes the gearing by about 5.6%. A bigger pinion loads the motor and ESC harder, so check the maker's gearing chart and feel the motor temperature after a run. Spur The large gear the pinion drives. A bigger spur with the same pinion gears the car shorter. Pinion and spur must have the same pitch, or tooth size, to mesh. The Gearing parts table below shows this car's pitch and part numbers. Transmission & axle Every reduction after the spur, multiplied together: transmission, differentials and axle gears. It is fixed by the design; the gearing you change is the pinion and spur. Final drive How many times the motor turns for one turn of the wheels. A higher number is shorter gearing: more acceleration and pulling power, less top speed.

Wheels & tires
Tire diameter The outside diameter of the mounted tire, tread to tread. A taller tire covers more ground each turn, which gears the car taller. At high speed tires can balloon and grow, so the real gearing gets taller as the car goes faster. Wheel hex The hex on the axle that the wheel locks onto and is driven by. A wheel must match the hex size to fit. 12 mm is the common size on 1/10 cars, so most 1/10 wheels fit; offset and width still vary. The wheel nut is a separate size, so check its thread too before buying nuts.

Power
Motor Brushed motors are rated by can size and turns rather than KV, so there is no KV to show. Motor shaft The diameter of the motor's output shaft. A pinion's bore, the hole in its middle, must match it. Battery The highest LiPo cell count the maker rates the electronics for. Each cell is 3.7 V nominal and 4.2 V fully charged. 3S is 11.1 V nominal and 12.6 V off the charger. Running more cells than this risks the ESC and motor. Many cars also run on fewer cells, only slower. Stock motor The motor fitted at the factory, as the maker names it. Brushed motors are often named by can size, such as 540 or 550, and by turns: fewer turns is faster. Stock ESC The electronic speed control. It feeds power from the battery to the motor as you work the throttle, and usually powers the receiver and servo too. An amp figure in its name is normally the maker's continuous rating. A brushed ESC cannot run a brushless motor. Set its low-voltage cutoff for LiPo, so a pack is not run flat.

Performance
Theoretical top speed A brushed motor has no KV rating, so no theoretical top speed is worked out. Compare gearing by rollout instead.

Size & weight
Length Overall length as the maker states it, usually with the body fitted. Useful for comparing real size, since scale labels are loose. Width Overall width as the maker states it, usually with the body fitted. A wider car is more stable in corners and harder to roll over. Height Overall height as the maker states it, usually with the body fitted. Useful when checking it fits a shelf, a bag or a car trunk. Wheelbase The distance between the front and rear axle centers. A longer wheelbase is steadier at speed and over bumps; a shorter one turns more tightly.

How to read these figures

Stock is as the vehicle ships.
Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart.
Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor.
Not published means it exists but no source we could find prints it.

About teeth, pitch and bore

Tooth counts are the ones in the specifications above.
Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close.
Bore is the pinion’s hole, listed separately from the motor shaft (3.2 mm on the stock motor).

How these numbers were settled

The Blackout XBE manual's parts identification page lists a BS214-006 marked '18T Motor gear', and its exploded view lists the BS213-026 spur marked 'Spur Gear 55T'.

Redcat's part page for BS213-026 prints 'Spur Gear 55T (.8 Module)' and names the Blackout XBE in its fitment list.
The reduction after the spur is left blank because the diff unit (BS903-104) and the gear shaft unit (BS213-025) are sold without tooth counts, so the final drive is blank too.
The tire diameter comes from Redcat's part page for the black pre-mounted 1/10 truck tires and wheels (BS214-009), which prints an overall diameter of 109mm and a width of 47mm and names the Blackout XBE.
The manual lists the same part.
The manual's specifications page gives 427 mm long, 280 mm wide, 140 mm high without body and a 290 mm wheelbase, and a 7.2v NiMH pack in the box.
Redcat's page for the Hobbywing brushed waterproof ESC (the BS218-015 in the manual) lists the Blackout XBE and gives 'Max Battery: 3s 11.1v Lipo', while Redcat's page for the 550 motor lists a 2s limit, so the speed control's 3S rating is used here.
The motor is a 550 brushed can, so no KV applies.
Redcat's own page for the XBE on archive.org from 28 April 2015 describes the RC550 brushed motor and the 7.2v 3000mAh battery.
